ENVELOP.

Specification of Letters Patent. Patented J an. 1919.

Application filed November 13, 1915. Serial No. 61,402.

.Middlesex and Commonwealth of Massachusetts, have invented a new anduseful Improvement in Envelops, of which the following is aspecification, accompanied by drawings forming a part of the same.

The envelop forming the subject of our present invention is designed forinclosures which may require a memorandum thereof upon the envelopitself for permanent preservation, and a corresponding memorandum upon adetachable flap capable of being preserved as an inclosure in theenvelop.

It is the object of our invention to provide an envelop having the abovenamed characteristics and capable of being made including the operationsof gumming and .folding upon envelop machines now in common use.

Further objects of our invention are to bring the detachable flap intocontact with an unfolded side of the envelop in order that theinscription uponthe outer surface of the detachable flap may betransferred to a smooth and unfolded surface by means of an interposed.carbon paper, and also to bring the, inscription u on the detachableflap .and its'carbon duphcate upon the body of the envelop upon the sameside of the envelop blank previous to its being folded as in order thatany rinted matter, accompanying the inscription may be placed upon theenvelop by a single operation.

The above objects we accomplish by the envelop illustrated in theaccompanying drawings and hereinafter described, the

novel features beingpointed out in the appended claim.

Referring to the accompanying drawings,

- Figure 1 represents an envelop blank in its extended form showing theshape of the blank previous to folding, the surfaces to which gum isapplied, and the lines upon which the blank isto be folded.

Fi 2 shows the completed envelop with the et'achable flap. removed, 'andwith the seal flap folded over the-back of the envelop.

Fig. 3 represents the back side of the completed envelop, with thedetachable flap removed, and having the seal flap folded side of theenvelop.

Fig. 4 represents the front sideof the 'envelop with the. detachablefiapextended to disclose printed matter upon the face. of the envelop.

Fig. 5 represents a front view of the envelop with the detachable flapfolded upon the face of the'envelop, showing printed matter upon thedetachable'fiap corresponding to similar printed matter upon the face ofthe envelop, as shown in Fig. 4.-

Fig. 6 represents a sectional view of the envelop with the detachableflap extended in the osition shown'in Fig. 4. Fig. represents apreferred form of car bon sheet for interposing between the detachableflap and the face of the envelop for the purpose of allowing independentmemoranda to be inscribed upon the on. I

velop I Similar reference characters refer to simibroken lines 2, 3, {land 5.forms an unfolded body portion, the outer side of whichconstitutes the face of the envelop. The rectangular section 8 includedbetween the sides of the blank and the broken lines 3 and 9 formstheback flap of the envelop and is .of the same size as the rectangularbody portion 7. The broken line 9 represents a line of perforationsseparating the back flap 8 from a rectangular portion 10 forming adetachable flap, the length and Width of which is preferably slightlyless than the size of the back flap 8, in order to allow the flap whendetached to be inserted readily within the envelop.

The blank represented in Fig. 1 is folded as follows :--The first fold1s upon the broken line 2 turning over the extended portion 11 upon thebody portion 7 of the envelop in order to form a seal flap tucked withinthe envelop, but capable of being withdrawn in order to close theenvelop after the detachable flap has been removed. The blank is nextfolded upon the broken line' 3, turningover the back flap 8 to coverturning over the narrow end flaps '12 and '13, said end flaps beingfolded with their gummed surfaces 6 in contact with the outer:

.. side of the back flap 8, thereby completing the envelop, its finalform being represented n front view in Flg. 4, and in sectional vlew 1nFig. 6.

-While the blank 1 is in its extended form, we print upon the reversesides of the body,

portion 7 and the detachable flap 10 corresponding printed matter, saidprinted matter being arranged upon the face of the envelop to correspondin position with the printed matter upon the detachable flap 10 when thelatter is folded down upon the q is transferred by the carbon paper tothe face of the envelop, as shownin Fig. 5. This printed matter .will bevaried according to the uses to which-the envelops are to be put. In thepresent instance, the printed matter consists of the broken lines 14 and15, arrangedfor any desired memorandum, the

date line 16 and adollarrline 17, withbroken' lines 18, 19 and-20 for anaddress, and a.

supplemental date line 21. Upon the face of the envelop are broken linescorresponding to the lines 14 to 20, inclusive, asjrepresente'd at 14',15, 16, 17, 18', 19, and 20',

but with the, date line 21 omitted, leaving a space for an additionalmemorandum as indicated by the broken lines 22.

Our-improved envelop is especially adapted for inclosing deposits for bank collection to be indicated by a memorandum upon the envelop andhaving a corresponding detachable memorandum which may be given to de:

positors. Our improved envelop is also especially adapted to facilitatethe collec-' tion of coupons upon which an income tax is payable. Insuch cases the prescribed form of certificate require d'by the internaltax collector may be printed upon the outside of the detachable flap 10,with suitable spaces prepared upon the facex7 for the transfer of thecarbon inscription, In order to prevent the transfer of the inscriptionupon the date line 21 and" to preserve a blank space for the memorandumat 22 on the face of the envelop-,we interpose a sheet 'of carbon paper23 corresponding substantially to the size of the detachable flap 10,

the detachable flap 10 in the position indicated by the broken line 25,Fig. 4'. The detachable flap is then folded upon themterposed carbonpaper and the whole may.

be held securely in place by a small metallic clip over the edge of theenvelop. The requisite inscription is then made upon the outer surfaceof the detachable flap 10 which envelop, the seal flap 11 withdrawn and.

folded over the back of. the envelop. We claim,

'An envelop of the class described, comprising an elongated rectangularbody,'an, integral ungummed seal flap extending fromone of the. longersides of the body,

narrow gummed end flaps extending from each end of the body, arectangular ungummed back flap of substantially the same size asthe bodyand having an ungummed extension projecting from the side opposite saidseal flap and shorter than the back flap,

said envelop being completed by folding-in the order named, folding theseal flap on'the body of the envelop, folding the back flap over theseal fla and folding the end flaps ap, the face of the envelopand theback of said extension having correover the back sponding' printedmatter thereon.
